Do any of you guys know what the GCWR is for a 1995 Isuzu NPR. The GVW is around 14,500K lbs. I hauled my new Kubota 161 with it today and it was OK, but working, even with 245K miles!! I don't have an owners manual, so relying on you guys for some help.

hello david,
it seems the towing capacity of the npr's is a tough one to answer. i have been trying to find the answer for a couple weeks. the best i have come up with is from an australian website that says they can only tow about 5000 lbs. at the same time i have also read about others towing 161's and other mini excavators. that seems to be a bit over 5000.
how did it tow yours? were you able to maintain speeds going up hills or was there a big dropoff? i am looking for a medium duty dump truck to tow about 12000 lbs. so i am curious how it is working out for you.
good luck,
metin

I have had my NPR since the spring and regularly have towed my Bobcat 331 and my CAT 257MTL. Both of those are in the 8500lb range. It is no speed demon, but it tows fine. It does work on hills/inclines. I figured that with a GVW of 14K lbs. the towing capacity would be better. I think towing my 161 is over the top for capacity and very illegal, it did do it and until I find a trailer for my F800 to tow with, I will use the NPR a couple of more times. The brakes on the trailer and truck are in very good condition which makes me feel better.

Thanks,please let me know what youfind out. I am really surprised that no one else has responded. I am sure we aren't the only ones that tow or want to tow with one of these great trucks.

just got an email from dan cutler at GM. it said the GCVWR for NPR is 1800. for an NPR HD 1950. hope this helps. the numbers aren't very encouraging.
take care,

Why are those numbers so low? How can these trucks haul loads on them but not behind them?

I think he means 18,000 and 19,500 which is about right for what those trucks can gross combine because of the lack of power. Those little 4cylinder engines are already sucking wind hauling a fully loaded truck.

I'am not so sure I would want to be hauling a 161 Kubota behind anything less than a 3 ton truck something like a F-650 Ford. You figure 161 is about 12,000lbs you add in the trailer say 6000lbs your up to 18,000lbs that is quite a bit of weight 9 ton.

You say the pin weight at the hitch will be 2700lbs which isn't much if you have a gooseneck a pintle hitch you will make a 2 ton COE squat pretty good.

So if you have 2700lbs of pin weight one of those cab overs must weigh 9000lbs empty the truck will gross about 11,700lbs plus the trailer gcw of 29,000lbs. A little heavy for small brakes on the truck you would have to make sure those trailer brakes are in premo shape ie no brake problems what so ever.

sorry guys, i was in a hurry when i wrote that and did leave off a zero. 18000 and 19500 is correct.
